七、初学.NET—GridView中添加行按钮实现查看详细信息

前端：将需要跳转的页面中GridView中设置成模板列，使用HyperLink 的Navigate属性的第一个参数绑定数据，第二个是格式化参数实现页面跳转。

<asp:TemplateField HeaderText="用户名" SortExpression="UserName">

            <ItemTemplate>

                  <asp:HyperLink ID="HyperLink2" runat="server"

                      NavigateUrl='<%#Eval("UserID","UserInformation.aspx?UserID={0}") %>' Text='<%#Eval("UserName") %>'></asp:HyperLink>

           </ItemTemplate>

        </asp:TemplateField>

后台：在绑定代码中Page.Request.QueryString["UserID"]使用接收发送过来的数据，再使用DataRowView行视图接收查询的行数据。然后用控件接收此行各列通过Rows索引返回的数据。除了可以返回普通文本数据外，还可以返回下拉框、单选框的数据，就需要提前将相应字段绑定到控件上。

private void SetBind()

    {

        DataSet ds = new DataSet();

        DataSet dsDepartment = new DataSet();

        using (SqlConnection conn = new SqlConnection(sConnectionString))

        {

          SqlDataAdapter da = new SqlDataAdapter("select * from tbUser  where UserID='"+Page.Request.QueryString["UserID"]+"' ", conn);

             da.Fill(ds);

             SqlDataAdapter daDepartment = new SqlDataAdapter("select * from tbDepartment",conn);

             daDepartment.Fill(dsDepartment);

             ddl_BelongToDepartment.DataSource = dsDepartment;

             ddl_BelongToDepartment.DataTextField = "DepartmentName";

             ddl_BelongToDepartment.DataValueField = "DepartmentID";

             ddl_BelongToDepartment.DataBind();

             ddl_BelongToDepartment.Items.Insert(0, "请选择系部名称");

          

           DataRowView dvUser= ds.Tables[0].DefaultView[0];

        lb_UserName.Text = dvUser.Row["UserName"].ToString();

        tb_UserPassword.Text = dvUser.Row["UserPassword"].ToString();

        tb_UserRealName.Text = dvUser.Row["UserRealName"].ToString();

        rbl_UserGender.SelectedValue = dvUser.Row["UserGender"].ToString();

        tb_Birthday.Text = dvUser.Row["Birthday"].ToString();

        ddl_EeducationBackground.SelectedValue = dvUser.Row["EducationBackGround"].ToString();

        rbl_InsideOrOutside.SelectedValue = dvUser.Row["InsideOrOutside"].ToString();

        tb_WorkUnit.Text = dvUser.Row["WorkUnit"].ToString();

        ddl_BelongToDepartment.SelectedValue = dvUser.Row["BelongToDepartment"].ToString();

        tb_Position.Text=dvUser.Row["Position"].ToString();

        tb_Tel.Text = dvUser.Row["Tel"].ToString();

        tb_QQ.Text = dvUser.Row["QQ"].ToString();

    

        }

    }
